Might want to consider xfi Advantage if you're going to be renting their modern and getting a speed tier at 250mb/s or above. It's $2 more than simply renting the modern and you get unlimited data. Unlimited data by itself can be up to $50.

Downside to xfi Advantage is that you have to use their modern. They're probably selling your metadata to China, but it beats having to budget your data to stay under the 1tb cap.
